Abstract:

Hanbury Brown-Twiss (HBT)results of the nucleon-nucleon correlation function have been presented for the nuclear reactions with neutron-rich projectiles (Be isotopes)using an event-generator, the Isospin-Dependent Quantum Molecular Dynamics model.It discusses the relationship between the binding energy per nucleon of the projectiles and the strength of the neutron-proton HBT at small relative momentum.Moreover, the relationship between the single neutron separation energy and the strength of the halo neutron-proton HBT is revealed.Results show that neutron-proton HBT results are sensitive to binding energy or separation energy.Some researches about the Equation of State (EOS)have been completed,which show that the HBT results are also sensitive to the parameters of the EOS.

Key words: IDQMD model, correlation function, nuclei reaction at intermediate energy
